Since C++23, the C++ standard library can now be imported as a module, but must be imported in its entirety rather than importing specific packages of the library like in Java, with import std;, or optionally if requiring the C standard library in the global scope, with import std.compat;.
] Some of the leading Java IDEs (such as IntelliJ and Eclipse) are also the basis for leading IDEs in other programming languages (e.g. for Python, IntelliJ is rebranded as PyCharm, and Eclipse has the PyDev plugin.)
Few languages ever become sufficiently popular that they are used by more than a few people, but professional programmers may use dozens of languages in a career. Most programming languages are not standardized by an international (or national) standard, even widely used ones, such as Perl or Standard ML (despite the name).

This additional functionality is available for C++ by (often free) third party libraries, but third party libraries do not provide the same ubiquitous cross-platform functionality as standard libraries. This point that Java is more portable than C++ is made throughout the article and bugs me. C++ was designed to be portable.
In C++ the memory and performance cost of these types of references can be avoided when the instance of B and/or C exists within A. In most cases a C++ application will consume less memory than an equivalent Java application due to the large overhead of Java's virtual machine, class loading and automatic memory resizing.
The designers chose to address this problem with a four-step solution: 1) Introducing a compiler switch that indicates if Java 1.4 or later should be used, 2) Only marking assert as a keyword when compiling as Java 1.4 and later, 3) Defaulting to 1.3 to avoid rendering prior (non 1.4 aware code) invalid and 4) Issue warnings, if the keyword is ...
High-level languages such as C++, Java, Smalltalk, and Visual Basic yield 5 to 15 times better productivity, reliability, simplicity, and comprehensibility than low-level languages such as assembly and C. Equivalent code has been shown to need fewer lines to be implemented in high level languages than in lower level languages. [7]
